ELKA Elastic

Perfect finishing of any surfaces with ELKA-elastic

ELKA-Elastic offers customizable solutions for your individual metal finishing requirements.

The range of grinding tools, based around an assortment of abrasive wheels bonded with elastic reaction resins, offer a custom solution for whatever your problem may be.

Aluminium oxide and silicon carbide are used as abrasive grains. In specific applications, diamond grains are also used. 

As resins are highly versatile, tools with a Shore hardness of A 30 (approximately the hardness of mattress foam) to D 95 (hardness of electro casting resin) are used. This special type of bonding allows the grain to oscillate, which in turn leads to gentle contact with the material to be ground. As a result, the removal rate is low, but a technically perfect surface is generated.

ELKA Elastic - Our Process

Our products are dispatched from our production plant in Wiedergeltingen, Bavaria, to companies across the world. These products assist in producing surfaces with technical and optical precision.

At our laboratory we develop solutions for individual applications, new product groups, innovations and serial processes.

We qualify our products and carry out preliminary tests in-house, and work together with our customers to define process chains. This saves time and costs.

Experienced employees and modern production guarantee the satisfaction of our customers. For you and your applications, too!

Porous elastic tools for non-specific solutions

Polishing, deburring, descaling, rounding and structuring with porous foamed abrasives are all established operations for processing parts and surfaces.

In all areas of production, elastic abrasives are used worldwide for rendering processes more efficient and comfortable, or even for making these processes possible in the first place.

Application Areas: Surgical instruments, cemented carbides, drive elements, spindles, shafts, jewellery, sheet metal

Compact elastic tools for precise machine processes

Surface processing with compact foamed tools is carried out in all technical areas in which conventional grinding tools reach their limits. Irrespective of whether a lubricoolant is used or not, the tool can be individually adapted to the process in an optimum way.

The defined degree of elasticity guarantees a harmonious process with minimized heat input. The geometry is generated according to customer specifications.

Application Areas: Tools, extruders, machine elements, rollers, blades

Precision

Tools made of synthesized plastics with a compact structure

These tools are used in precision processes. They often represent the finishing operation in a production process, during which the final technical specifications are ensured.

Here, surface values of Rz<0.5μm are achieved while still observing tight tol- erances and attaining an increase in technically relevant parameters such as the contact ratio.

The efficient, fast and uncomplicated product for your technical application.

Application Areas: Automotive, storage and transmission technology, aviation, electrical engineering 

Precision Cut

Additional cutting ability

Both the permanent further development of our bonding systems and the new development of bonding systems with various grain bonding strategies lead to diverse application possibilities, tailored to requirements from all areas of tech- nology.

In this way, we can achieve optimum surfaces, even with hardened materials. Rz<0.5μm.

Application Areas: Tools, automotive, transmission technology
